My understanding is that QEMU does not emulate bursts because it's a functional simulator rather than low-level PCI bus transaction simulator. You might be interested in KVM's coalesced MMIO feature. That is a performance optimization but it's not PCI-specific. Why are you trying to do PCIe bursts? Stefan
